Description: This object will give the minimum partition size supported for this device. For systems that execute code directly out of Flash, the minimum partition size needs to be the bank size. (Bank size is equal to the size of a chip multiplied by the width of the device. In most cases, the device width is 4 bytes, and so the bank size would be four times the size of a chip). This has to be so because all programming commands affect the operation of an entire chip (in our case, an entire bank because all operations are done on the entire width of the device) even though the actual command may be localized to a small portion of each chip. So when executing code out of Flash, one needs to be able to write and erase some portion of Flash without affecting the code execution. For systems that execute code out of DRAM or ROM, it is possible to partition Flash with a finer granularity (for eg., at erase sector boundaries) if the system code supports such granularity.

This object will let a management entity know the minimum partition size as defined by the system. If the system does not support partitioning, the value will be equal to the device size in ciscoFlashDeviceSize. The maximum number of partitions that could be configured will be equal to the minimum of ciscoFlashDeviceMaxPartitions and (ciscoFlashDeviceSize / ciscoFlashDeviceMinPartitionSize).

If the total size of the flash device is greater than the maximum value reportable by this object then this object should report its maximum value(4,294,967,295) and ciscoFlashDeviceMinPartitionSizeExtended must be used to report the flash device's minimum partition size.
